COMBINED LOCK AND LA'i'CH.

SPECIFICATION forming part of Letters Patent No. 541,801, dated June 25,1895.

Application filed October 5, 1894.

To all whom it may concern.-

Be it known that 1, JAMES H. BARRETT, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and use ful Improvements in a Combined Lockand Latch; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to combined locks and latches.

My object is to provide a combined lock and latch, specially adapted tocases where a very tight fit is required between the door and the jamb,for preventing the escape of air as in refrigerators and similar doors.

The invention consists in the peculiar construction, combination andarrangement of. the parts hereinafter described and particularly pointedout in the claims, reference being had to the accompanying drawings,which, with the letters of reference thereon, form a part of thisspecification, and in which- Figure 1 represents an elevation of acombined lock and latch, constructed in accordance with my invention,with the front plate of the casing broken away to show details, and

0 Fig. 2 a horizontal section-of the same, on the line 2 2 of Fig.1.

A represents the lock casing, provided at one end with an opening, inwhich moves the projecting beveled end of the spring actuated latch, andat the opposite end with an opening for the handle, and A is the frontplate of the casing broken away in Fig. 1, as stated.

Bis the strike plate or keeper, the front plate B of which is brokenaway in Fig, l.

G, is a combined latch and handle, formed integral, constructed in the Lshaped form shown, having the pendulous vertical arm c pivoted at itsupperend on the post F, a spur (0 at the back lower corner of the Lproject- 5 ing through the casingand engaging with the keeper, andhaving the rounded face 0 the horizontal upwardly curved long armportion0' inside the casing, and the outwardly projecting oppositely curvedportion 0 outside of the casing forming the handle. D, is the Serial No.525,023. (No model.)

spring which actuates the latch and E, the lug behind the spring, whichholds it in place.

G, is a plate or casting for locking the latch and has the semicircularopening g, the projecting portion g between the lugs I, I, and theprojecting portion g between the lugs J, J. When unlocked, this castingis in the position shown in Fig. l, but when the key is inserted andturned around, the guard of the key engages the lower side and lifts itto the position shown in dotted line in the same figure, the armsbearing against the back of the portion 0 of the latch, and theprojecting portion g engaging the lug J, upon the opposite side, therebypreventing lateral movement of the latch.

H, is a post on the front plate, in which, upon the opposite end, is thescrew (not shown) which holds the back plate in position, and K, is aspring for the casting G.

Itwill now be seen that by grasping the handle c the curved face 0engagingthe plate B of the keeper, the door may be forced against thejamb as with a lever, the fulcrum of which is the post F, bypulling downupon j the outwardly projecting handle, which forms the long arm of theL shaped structure; the opposite, or short arm 0 forming the catch bolt,being really a continuation or prolongation of the handle, whereby Iobtain great purchase for forcing the door tight, on account of thewedging of the rounded face 0 against the face B of the keeper B. Inother words, down stroke of the handle, produces lateral movement of thecatch.

I claim l. The combination with the casing and the L-shaped integralcombined latch bolt and handle pivoted at the upper end of its vertical.arm, to swing laterally in said casing, and having the laterallyprojecting portion 0 to form the catch asset forth, of the locking plateor casting G, arranged behind said vertical arm, adjusted to bealternately moved, to engage with and recede from said vertical arm, 5having the portion g engaging the lugs J, J, the portion 9 arrangedbetween the guide lugs I, I, and the spring K, engaging the end thereof,for holding the same in place, substantially as set forth.
